XY Underwater Battles! And perhaps even more?

[Ghost King]

Maybe Pokémon that aren't water types receive damage every turn like sandstorm when underwater?

EDIT: Ninja'd xD

I agree, but then shouldnt they agree that would happen shouldnt they introduce a new move that makes water rises on the field? It really doesnt make sense that rock, ground, and fire types are underwater like charmander underwater in the pokedex its said that if its flame on its tail goes out they die.
